Cast
Cast is a Go type conversion library and data type casting utility designed to transform various primitive data types into specific target formats. It functions as a primitive type transformer that manages the conversion of basic Go types while handling incompatible data.
The library provides mechanisms for dynamic type handling, allowing the system to process untyped or interface data and safely cast values into concrete types during runtime. It includes logic to distinguish between successful zero-value results and failed conversions through explicit error reporting and validation.
Features
- Primitive Type Converters - Provides utilities for transforming values between basic primitive types like strings, integers, floats, and booleans.
- Data Type Casting - Provides a comprehensive utility for casting data types with built-in validation and error handling.
- Conversion Validation - Convert data to a target type and return an explicit error to distinguish failed conversions from successful zero values.
- Dynamic Type Casting - Manages untyped or interface data in Go by safely casting values into usable concrete types during runtime.
- Interface-Based Data Handling - Accepts empty interfaces to allow the system to process any arbitrary data type before attempting a cast.
- Primitive Type Converters - Converts various primitive data types to a specific target format within Go while handling incompatible types.
- Primitive Type Transformers - Safely casts various basic Go data types into specific target formats.
- Type-Based Dispatching - Uses Go type switches to dynamically select the appropriate conversion logic based on the input's runtime type.
- Zero-Value Fallbacks - Returns the default value of a target type when a conversion fails to prevent application crashes.
- Static Conversion Paths - Defines static conversion paths between numeric and string primitives to ensure consistent data transformation.
- Data Type Validation - Ensures data conforms to expected Go types through conversion attempts and explicit error reporting.
- Error Wrapping - Implements custom error wrapping to distinguish between invalid input data and successful zero-value conversion results.
- Development Utilities - Safe data type conversion library.
